Need to vent?!?!

My husband has lost his job and we have bills coming up in the next two weeks and we don't have any Christmas presents for our two boys and he is leaving to go to his cousins wedding in Tennessee next week for 4 days.. I don't think he should go so he can continuing working odd jobs to keep making as much money as possible but I tried to tell him that I don't think he should go but he says he can't back out on the wedding well that makes me feel like his cousin is more important than his wife and kids.. am I overreacting???
